Endo-beta-1,4-D-mannanase is the key depolymerizing enzyme for beta-1,4-mannan polymers present in the cell walls of plants and some algae, as well as in some types of plant seeds. Endo-1,4-beta-mannanase from blue mussel Mytilus edulis (MeMan5A) belongs to the glycoside hydrolase (GH) family 5 enzymes. The MeMan5A structure has been determined to 1.6 angstrom resolution using the multiple-wavelen

The presence of cholinergic nerve fibers in the brain vasculature has been a matter of controversy, partly due to the lack of a reliable histochemical marker. Accordingly, no distinct information about the origin and pathways for such fibers has been available. In the present study on the rat pial vasculature, utilizing a choline acetyltransferase (ChAT) antibody, which is able to demonstrate this

Aim: To survey the entire population (n = 116) afflicted with severe haemophilia A or B born in Sweden over a 20-y period (1980-1999), and to examine the epidemiological, genetic and clinical aspects of development of inhibitors to factors VIII and IX (FVIII/FIX). Methods: One hundred of the subjects had haemophilia A and 16 had haemophilia B. All of these subjects had received prophylactic treatm

Circulating levels of insulin-like growth factor-I (IGF-I) and insulin-like growth factor-binding protein 3 (IGFBP-3) vary considerably between normal individuals. Recent epidemiological studies have provided evidence that these levels are predictive of risk of several common cancers. To evaluate possible sources of variation of the levels of circulating IGF-I and IGFBP-3 in females, we studied sp

Stimulation of human fibroblasts by platelet-derived growth factor (PDGF)-BB leads to a down-regulation of PDGF beta-receptors and a concomitant appearance of intracellular granular accumulations of receptors, as determined by stainings with the mAb PDGFR-B2. The granules contained both the ligand and PDGF beta-receptors, as revealed by double-immunofluorescence staining, and were formed in respon

Species richness in vascular plants was related to the plants' calcifuge or calcicole behaviour using documentation from forests and open-land vegetation at about one thousand sites in the southern parts of Sweden. It is concluded that vegetation of strongly acid soils (pH-KCl < 4.5) have fewer vascular plant species than comparable vegetation of other soils, whereas there are no consistent differ

The need to reduce CO₂ emissions from fossil-fuel based power production creates the need for new power plant solutions where the CO ₂ is captured and stored or reused. Oxygen Transfer Membrane (OTM) is the key component of oxy-fuel combustion processes as pure oxygen is usually required to process reactions (e.g. Natural Gas Combined cycle NGCC, Pulverised Coal-fired power p

The variation of the drag (CD) and lift coefficients (CL) of two fixed solid spherical particles placed at different positions relative each other is studied. Simulations are carried out for particle Reynolds numbers of 50, 100 and 200 and the particle position is defined by the angle between the line connecting the centers of the particles and the free-stream direction (a) and the separation dist

Popular Abstract in Swedish I centrum för min avhandling står den spanske dominkanen Alonso de Montúfar (ca.1489-1572) som mellan 1554 och 1572 var ärkebiskop av Mexiko. I synnerhet har jag studerat hur ärkebiskop Montúfar ville att kyrkan skulle organiseras (hans kyrkovision) och hur han försökte förverkliga sin vision (hans kyrkopolitik). Montúfar kom till Mexiko drygt trettio år efter den spanThis dissertation focuses on Archbishop Alonso de Montúfar OP (ca. 1489-1572). It seeks to explore two decades of sixteenth century Mexican Church History mainly through the study of documents found in Spanish and Mexican archives. Born outside Granada in Southern Spain, just after the conquest from the Muslims, Alonso de Montúfar assumed teaching and leading positions within the Dominican order.

We made a detailed study of the hoverflies on a small farm in the parish of Stenbrohult, southern Sweden in 2004-2007. The study area is totally about 17 ha, consisting of 9 ha of semi-natural grasslands with both dry and wet parts (recently mainly grazed by cattle and a few horses in late summer-autumn), a few hectares of old deciduous forest dominated by Fagus, Quercus, Betula, Populus tremula,

Popular Abstract in Swedish Avhandlingen handlar om litteraturläsning och litteraturundervisning i grundskolan. Syftet är att belysa den betydelse läsning av skönlitteratur ges i skolans mellanår i början av det tjugoförsta århundradet. Forskningsfrågorna berör de mål och föreställningar om litteratur och läsning som lärare ger uttryck för och hur dessa kommer till uttryck i konkret klassrumsarbetThis dissertation explores the teaching of literature in Swedish compulsory school. The aim of the study is to elucidate different approaches to literature instruction in upper elementary school (grades 4-6, pupils aged 10-13). The research questions focus on what goals and ideas about literature and reading guide teachers and how these are carried out in pedagogical practice and classroom activit

Popular Abstract in Swedish Elektrolyter är ämnen som sönderdelas i ett lösningsmedel och därvid ger upphov till positivt och negativt laddade joner. De starka elektrostatiska krafter i lösningen som detta i sin tur orsakar är typiska för elektrolytlösningar. Redan vid små tillsatser av en elektrolyt till ett lösningsmedel kan lösningens egenskaper förändras kraftigt. Lösningar av elektrolyter speA thermodynamic model for electrolyte solutions has been derived for binary and multicomponent solutions up to very high molalities. The model was extensively tested on 163 binary aqueous electrolyte systems up to very high molalities, and the results show that the model represents mean ionic activity coefficients and osmotic coefficients very accurately. The model parameters vary significantly be

In a cross-sectional study of diabetic patients diagnosed at or after 30 years, and with different stages of retinopathy, factors such as duration of diabetes, treatment mode, metabolic control, blood pressure, and clinical signs of nephropathy were examined. The different stages of retinopathy used were absence of retinopathy, simplex, and severe retinopathy. Patients with simplex and severe reti

A method based on computational fluid dynamics (CFD) for the characterization of static mixers using the Z factor, helicity and the rate of striation thinning is presented. These measures were found to be well-suited for the characterization of static mixers as they reflect the pressure drop, the formation of secondary flow, i.e. vortices, and their effect on the mixing process. Two commercial sta

Over the past few decades, numerous wide (> 103 au) binaries in the Galactic field and halo have been discovered. Their existence cannot be explained by the process of star formation or by dynamical interactions in the field, and their origin has long been a mystery. We explain the origin of these wide binaries by formation during the dissolution phase of young star clusters: an initially unbound
